Benefits of technology

The invention provides a cable water stop structure that prevents water from getting inside the sheath where wires are exposed. This stops water from getting inside and damaging the wires. The patent is for a wire harness that uses this structure to ensure safety and reliability.

Problems solved by technology

Even if the sheath and the insulated wires extending from the end of the sheath are collectively covered with a single heat shrinkable tube, the water stop property may not be ensured under a high-temperature environment of, e.g., 120° C. or more, since the resin tube may be shrunk again and detached from the sheath at the high temperature.

embodiment

[0035]An embodiment of the invention will be described below in conjunction with the appended drawings.

[0036]Description of a Vehicle in which a Wire Harness is Used

[0037]FIG. 1 is a schematic diagram illustrating a configuration of a vehicle in which a wire harness in the present embodiment is used.

[0038]A vehicle 1 has four wheel-wells 100 on a vehicle body 10, and two front wheels 11 and two rear wheels 12 are respectively arranged in the wheel-wells 100. In the present embodiment, the vehicle 1 is a front-wheel-drive vehicle and the front wheels 11 are driven by a drive force from a drive source (not shown) such as an engine or electric motor. In other words, in the present embodiment, the front wheels 11 are drive wheels and the rear wheels 12 are non-driven wheels.

[0039]The vehicle 1 also has two electric parking brake units 130 and a control unit 14. The electric parking brake units 130 are provided so as to respectively correspond to the two rear wheels 12, are activated by ...

Abstract

A cable water stop structure for a cable that includes plural insulated wires and a sheath covering the plural insulated wires includes a heat shrinkable tube that is shrunk to wrap around an end of the sheath and the plurality of insulated wires extending from the end, and a cover that is attached to sandwich the end of the sheath, the plurality of insulated wires extending from the end and the heat shrinkable tube. The cover includes a gripping portion gripping the heat shrinkable tube to restrict the heat shrinkable tube from moving along a cable longitudinal direction.

Description

[0001]The present application is based on Japanese patent application No. 2017-094248 filed on May 10, 2017, the entire contents of which are incorporated herein by reference.BACKGROUND OF THE INVENTION1. Field of the Invention[0002]The invention relates to a cable water stop structure and a wire harness using the cable water stop structure.2. Description of the Related Art[0003]In recent years, electrically operated brake systems are used in a vehicle such as an automobile. The known electrically operated brake systems include an electro-mechanical brake (EMB) system and an electric parking brake (EPB) system.[0004]The electro-mechanical brake system, which is also simply called electric friction brake or electric brake, is configured such that a rotational drive force of a dedicated electric motor mounted on each wheel of a vehicle is controlled according to the operation amount (tread force or displacement amount) of a brake pedal by a driver, so that a piston driven by the elect...
